Created attachment 119582 [details] Picture Please look at the picture. It want to add an yahoo account and I was asked for google.
Same problem on opensuse leap 15.1 (kmail2 5.10.3)
Problem still existed. Please take it into account. Thanks
If you are still able to reproduce this with 20.04.2, please try adding a mail account not using the account setup helper but via KMail -> Accounts -> Receiving -> Add [Custom Account] (If you choose 'Add Mail Account' it will start the account setup helper again.)
I experience the same on manajaro 20.1 testing. I can manually configure as an IMAP server. However yahoo will no longer be supporting this starting October 20
